耕地壟 的英文怎麼說
中文拼音 [gēngdelǒng]
耕地壟
英文
ploughed furrow-
In the course of working, ， the plow will make use of the shuttling method so that it can dig alternately either on the left or on the right. compared to the unilateral plow, it can improve the productivity because it can help leave off the soil 、 take from the consumed energy and reduce the empty journey. to meet the requests above, we will use a remote cylinder with both a small cubage and double functions, approximately designing the plow to be columniform and symmetric. after the experiment for a period in the field, we found that the most frayed areas had happened at the places of both plow shank and share and at the same time the base of the remote cylinder had ruptured suddenly
與單向犁相比，其優點在於：耕地無開、閉壟，地表平整，降低了耕后整地的能量消耗，減少了地頭的空行程，因而大大提高班次生產率。為了滿足犁體梭式作業的要求，我們採用了一隻小容積雙作用的液壓油缸；同時對犁壁曲面的形狀採用了近似圓柱形的對稱設計。但經過一段時間的田間試驗，我們發現：該犁犁胸部分的犁脛和犁鏵上的犁尖在工作中磨損較為嚴重；主犁梁和油缸缸體的連接部分（即油缸底座）突然發生了斷裂，造成整個犁體無法正常工作。The elementary idea of the reference units method can be described as follows : firstly, by the setting of double series of reference units, we can control the highest and lowest land quality class of each village or town ; secondly, the class of the arable land will be get through the contrast between the arable land with the reference unit which has been selected in the same area, the difference in quality is the key factor to classify the land. the results show, 87. 6 % of the lands from i to iii distribute on alluvial and lacustrine plains, where the associated soils are mainly grey fulvo - aquic and calcareous concretions black ones. and 61. 4 % of them from iv to vi distribute on slightly rolling parts with mainly yellow - cinnamon soil developed from the diluvial and slope deposits
分等結果表明：臥龍區等的耕地中，有87 . 6分佈在沖積、湖積平原區，主要土壤類型是在河流沖積物上發育形成的灰潮土、在湖相沉積物上發育形成的砂姜黑土；等耕地中，有61 . 4分佈在壟崗區，主要土壤類型是洪坡積物上發育形成的黃褐土：而、等耕地集中分佈在丘陵區，主要土壤類型是殘坡積物上發育形成的粗骨性黃褐土，等別結果分佈總體上體現了不同地貌類型、土壤條件下耕地質量的差異。Application of hillside cultivated alleg directed regional field technique
坡耕地壟向區田技術的應用4. at 8 ? slope land areas, the sequence of increasing production benefit of different cultivation is : mulching > plastic mulching > furrow and ridge tillage > traditional product
在黃?土地區的8坡地上，不同耕作措施對小麥的增產效益按大到小的順序是：覆蓋覆膜等高溝壟直線坡。6. the order of the effect to wheat productivity in different combination of tillage and application rate is : mulching + high application rate > mulching + middle application rate > plastic mulching + high application rate > furrow and ridge tillage + high application rate > plastic mulching + middle application rate > furrow and ridge tillage + middle application rate, etc. mulching is easy and with better benefit, so should popularize
耕作措施與施肥量的不同組合對黃?土坡耕地小麥產量的影響作用中，按增產效益排序的前幾個較優組合為：覆蓋+高肥覆蓋+中肥覆膜+高肥溝壟+高肥覆膜+中肥溝壟+中肥。覆蓋耕作與肥料的組合簡單易行且效益較好，所以應加以推廣。According to the valuation of 1831, there were in concord two thousand one hundred and eleven acres, or about one seventh of the whole territory in meadow ; this standing next in the list after pasturage and unimproved lands, and, judging from the returns of previous years, the meadow is not reclaimed so fast as the woods are cleared
根據1831的評估，康科德有兩千一百一十一英畝的土地，整個區域大約有七分之一處于草甸中；這些未砍伐的區域位於牧場和未耕種土地之外的田壟里，並且以前一年的結果來看，樹木一旦被砍伐掉，草甸就無法再生了。In research much importance was attached to the study of dry land and the physical, chemical and biologic properties of water land, but the relationship between soil microbes and soil fertility in the paddy field of long - term no - tillage and ridge culture was relatively ignored, so this experiment was conducted for further study
縱觀國內外的研究概況，對旱地的研究比較多，對水田的物理、化學和生物性狀也有研究，但是，對稻田長期壟作免耕條件下的土壤微生物和肥力的關系的研究尚鮮見報道，因而著手于這方面的研究。分享友人
